如何從JetPack4.3 和 JetPack4.4 DP 版本升級SDK到JetPack4.4版本?

NVIDIA提供從JetPack 4.4開始，升級到下一個JetPack版本可以直接使用DEBIAN包管理工具而不用直接燒錄的方式，按照以下步驟執(zhí)行升級:

1. 升級JetPack 組件包

$sudo apt install nvidia-jetpack

如果存儲空間有限則可以先移除舊包（如16GB EMMC），參考命令 :

#如下移除JetPack4.3 的SDK 包
$sudo apt autoremove --purge nvidia-container-csv-cuda libopencv-python libvisionworks-sfm-dev libvisionworks-dev libvisionworks-samples libnvparsers6 libcudnn7-doc libcudnn7-dev libnvinfer-samples libnvinfer-bin nvidia-container-csv-cudnn libvisionworks-tracking-dev vpi-samples tensorrt libopencv libnvinfer-doc libnvparsers-dev libcudnn7 libnvidia-container0 cuda-toolkit-10-0 nvidia-container-csv-visionworks graphsurgeon-tf libopencv-samples python-libnvinfer-dev libnvinfer-plugin-dev libnvinfer-plugin6 nvidia-container-toolkit libnvinfer-dev libvisionworks libopencv-dev nvidia-l4t-jetson-multimedia-api vpi-dev vpi python3-libnvinfer python3-libnvinfer-dev opencv-licenses nvidia-container-csv-tensorrt libnvinfer6 libnvonnxparsers-dev libnvonnxparsers6 uff-converter-tf nvidia-docker2 libvisionworks-sfm libnvidia-container-tools nvidia-container-runtime python-libnvinfer libvisionworks-tracking

2. 如果機器中已使用SDK管理器安裝了JetPack，需刪除本地repo

#如下移除JetPack4.3 本地repo
$sudo apt purge cuda-repo-l4t-10-0-local-10.0.326 libvisionworks-repo libvisionworks-sfm-repo libvisionworks-tracking-repo

3. 釋放apt 緩存空間

$sudo apt clean

4. NVIDIA OTA 對L4T進行升級，參考： NVIDIA Jetson Linux Developer Guide.

### How to Install Debian Packages with OTA Update
1.輸入命令獲取APT 升級倉庫列表:
$sudo apt update

2.輸入命令顯示可更新升級的軟件包:
$apt list --upgradable

3.輸入命令升級L4T包:
$sudo apt upgrade

4.以上三步更新完成后，重啟機器
1.打開apt source:
$ sudo vi /etc/apt/sources.list.d/nvidia-l4t-apt-source.list

2.修改倉庫名稱及URL 地址（deb）
原始數(shù)據(jù):
deb https://repo.download.nvidia.com/jetson/common r32 main
deb https://repo.download.nvidia.com/jetson/<platform> r32 main

其中 <platform> 表示對應(yīng)平臺的處理器:
?t186 for Jetson TX2 series
?t194 for Jetson AGX Xavier series or Jetson Xavier NX
?t210 for Jetson Nano or Jetson TX1

修改后 r32 為 r32.4并對應(yīng)準確的平臺信息如Jetson Xavier :
deb https://repo.download.nvidia.com/jetson/common r32.4 main
deb https://repo.download.nvidia.com/jetson/t194 r32.4 main

3.保存并關(guān)閉apt source 配置文件

4.輸入命令更新:
$ sudo apt update
$ sudo apt dist-upgrade

如果要求輸入configuration 文件選擇，點擊Y(yes)

5.待更新完成后，重啟機器

5. 安裝新的JetPack 組件包

$apt depends nvidia-jetpack | awk '{print $2}' | xargs -I {} sudo apt install -y {}
